Description

Factory Manufacturing Execution System Combined with Standard Operating Procedures

technical field

The present invention relates to a factory manufacturing execution system (Manufacturing Execution System, MES), in particular to an information system that can share standard operation information in combination with an electronic standard operation support system (ESOP).

Background technique

In order to enable managers to issue effective orders and manage factory activities, the industry has developed a management system that can transmit the status and information of factory activities to managers. This system is called the Manufacturing Execution System (Manufacturing Execution System, MES), also known as "Shop Floor Integrated System (SFIS)", or "Shop Floor Control System (SFCS)". For example: the "on-site control information system" of the published Taiwan Patent Announcement No. 200424891, which discloses a system that includes a Web server, an enterprise website, a database, an enterprise production control system, and multiple clients and workstations. The on-site control information system of the client is used to query and analyze the on-site control information of the workstation and monitor the on-site operation of the workstation.

In terms of production operations, through the implementation of a standard operating procedure (Standard Operation Procedure, SOP) to reduce the defect rate caused by human error, and to achieve cost reduction and uniformity of quality production, and SOP can be defined as: "For regular It is a written document that describes the execution process in detail in order to make the program consistent and standardized, such as various inspections, operations, operations, etc., for repetitive or repetitive work; in other words, the basic concept of standard operating procedures It is to standardize and unify the job information in the execution process of a certain job.

In general, there are some issues with the way Standard Operating Procedures (SOPs) are implemented, including:

1. The operation information of standard operating procedures is recorded in paper documents. It takes a lot of time to plan and make these paper documents, and paper documents are not easy to save and manage.

2. The update and change of the content of the standard operating procedure is slow and inconvenient. In today’s diversified production line tasks, it is difficult to record the information of the standard operating procedure in paper documents if the production task changes or there are some minor adjustments. Quickly update or change the recorded operation information.

A laboratory information management system (laboratory information system) is disclosed in the published U.S. Patent 2001/0034756 A1, which discloses a SOP-oriented system architecture, using this information system to assist scientists in experiments and related management of routine work and documents; in addition, a management system and method for group work is disclosed in the published US Patent 2002/0065704A1, which is used to support multiple workers to carry out products with multiple development steps For the collaborative development of manufacturing technology, the system and method can quickly convey the information about the development work to each technology developer, and at the same time, can obtain the application software information and operation progress information required for the development process.

However, the above known art still does not disclose any solution that can integrate the Standard Operating Procedure (SOP) with the Plant Information Integration System (SFIS).
